Astra Stalling Issues: Camshaft Sensor Suspect?

Hey there! I had a very similar issue with my 2009 Vauxhall Corsa last year (I've got some experience working on cars, but nothing too fancy). Those symptoms sound exactly like what I went through, the unusual stalling was super annoying! Turned out it was indeed the camshaft sensor playing up. Took it to my trusted local workshop, and they diagnosed it pretty quickly. The whole thing, including parts and labor, set me back about 695 Euro, but it fixed all those issues you're describing. Car's been running like a charm since then. Before I share more specifics about my repair experience, could you tell me which engine you've got in your Astra? Also, what's the mileage on it? That would help me give you more relevant info from my experience. Pro tip: Don't wait too long to get it checked, these sensor issues can get worse and potentially damage other components.

Thanks for sharing your experience! Mine's at 131371 KM and just had a service last month. I think you might be right about the camshaft sensor, the symptoms match up perfectly. Just wondering, did you notice any specific patterns with the stalling? Like, did it happen more when the engine was cold or warm? I'm trying to gather as much info as possible before taking it to the mechanic to avoid getting ripped off. Your repair cost seems reasonable though, good to have a ballpark figure in mind. The stalling's driving me nuts, especially when I'm stopped at traffic lights. Super embarrassing when it happens in traffic! Guess I'd better get it sorted sooner rather than later.

Hey again! Glad I could help. Yeah, with my Corsa, I definitely noticed some patterns with the stalling, it was actually worse when the engine was warm, especially during idle. Like, it would run okay-ish in the morning, but after about 15-20 minutes of driving, that's when it would start acting up. Super annoying at traffic lights, just like you mentioned! The embarrassing stalling situation? Been there, done that! I remember this one time at a busy roundabout, the car just died on me, and everyone behind was honking. Not fun at all! Your mileage is pretty close to what mine was when I had the issue (mine was around 140,000 KM). One thing I forgot to mention earlier, before I got it fixed, I noticed the problem got progressively worse over about two weeks. Started with just occasional problems, then turned into full-on stalling. Quick tip: When you take it to the mechanic, get them to check the sensor's wiring harness too. In my case, there was a bit of corrosion in the connector that they cleaned up while doing the replacement. Might save you from future headaches! Let me know how it goes with the repair. Always curious to hear if others have the same experience I did with these Vauxhalls!

Thanks so much for all the details! That's really helpful to know about the warm engine issues and the wiring harness tip. My situation sounds identical to yours, it's definitely getting worse over time, and yeah, those embarrassing stalling moments are the worst! Had my own roundabout drama just yesterday. I've actually just booked it in at my local garage for next Tuesday. Showed them your messages about the camshaft sensor and wiring connector, and they agreed it's likely the culprit. They quoted me around 650 Euro all in, which seems fair based on your experience. Really appreciate you taking the time to share all this, it's made me feel a lot more confident about getting it sorted. I'll probably stop driving it until Tuesday just to be safe. Don't fancy any more roundabout dramas! Thanks again for all your help!
